Often when I play players complain that there is a nasty wolf which cannot be killed by villagers. Especially in the beginning of a game with few villagers it makes huge difference. I found a way to avoid this problem. If wolf is attacking next to the warehouse or city center, the best thing to do is to hide ALL villagers in the warehouse/center for a second or two. The wolf will attack the warehouse/city center and completely disregard villager working away right next to the wolf. The rate of attack is such low that it doesn't create any noticeable damage. I attached a screenshot of this situation.
